Adrenaline autoinjectors are designed to be given by non-medical people, such as parents, school and childcare staff, friends, passers-by or the allergic person themselves (if they are well and old enough). Adrenaline autoinjector devices contain a single, fixed dose of adrenaline that works rapidly to reverse the episode of anaphylaxis. Instructions regarding correct use are included on the device labels, and on ASCIA Action Plans
